Sergio Alvarez from Colombia did a great job on his blog. A lot of useful example to build and use Pinguino:
- a step by step description to build Pinguino on a test board,
- What is sometime troobleshoothing with windows,
- How to use an I2C ultrasonic range finder ( this one could be integrated in the pinguino tutorial with sergio acknoledgement )
and a lot of well documented things.
And maybe a good way to learn spanish !!
